PROBLEM TO BE SOLVED: To provide an aluminum brazing method for a heat exchanger of various applications which is capable of suppressing the buckling of an interposed member and effectively effecting the brazing when the interposed member such as a corrugated fin and a flat pipe group are tightened and brazed. SOLUTION: In a method in which a flat pipe group coated with non- corrosive flux and metallic powder is arranged between header plates or header pipes, and tightened with an interposed member such as a corrugated fin interposed between the flat pipe groups, and then, brazed to manufacture an appliance such as a heat exchanger, the corrugated fin is formed of an aluminum alloy containing, by weight, 0.8-1.7% Mn and 0.3-0.8% Mg.
